A Short IPv6 Guide for Home IPv4 Admins

This guide is for homelab admins who understand IPv4s well but find setting up IPv6 hard or annoying because things work differently. In some ways, managing an IPv6 network can be simpler than IPv4, one just needs to learn some new concepts and discard some old ones.

Let’s begin.

First of all, there are some concepts that one must unlearn from ipv4:

Adding tailscale to an EdgeRouter (and surviving system upgrades)

I suggest you run sudo bash on all of these so you're the root user.

Installing

1. Download tailscale and put the files in /config/. Find the latest stable or unstable version for your EdgeRouter's processor (ex. ER4 is mips and ERX is mipself)

sudo bash    # if you havent already

Cask-Upgrade

Small utility to help you manage packages installed via Homebrew Cask as it currently can't upgrade installed packages for you or clean up old versions.

The script will ask you if you want to upgrade applications which has newer versions available. Downloads from previous versions of applications will be removed when an application is updated, like what Homebrew has been doing since version 2.0.0. This behaviour can be disabled by setting the environment variable HOMEBREW_NO_INSTALL_CLEANUP.
